13 Unlucky Numbers is the second album by Wax, and also marks their major label debut. The recording sessions took place during the summer of 1993 at Fort Apache Studios and were produced by Paul Q. Kolderie and Sean Slade. The album spawned the singles "California" and "Who is Next", both with music videos directed by Spike Jonze, who is also credited for the albums photography. Although the album lists 13 tracks, it only includes 10 songs, as the last three tracks are silent.
